tem - Senior Staff Engineer - Pricing Infrastructure (Rosso)
Requirements
• Exceptional technical leadership experience: Experience operating at Staff+ or Senior Staff level, with clear evidence of organisation-wide impact at a high-growth startup. • Architectural depth: Proven ability to design and evolve complex, stateful distributed systems spanning APIs, event-driven architectures, data systems, and front-end applications - where domain logic is the primary source of complexity. Proven patterns for high-throughput performance and scaling architecture to support hundreds of thousands of customers, while preventing domain drift. • Multi-team influence: Experience leading cross-team initiatives that directly impact revenue across engineering, product, data, machine learning, commercial and ops stakeholders. • Modern tech expertise: Deep experience with: • AWS serverless architecture (Lambda, API Gateway, DynamoDB) • Event-driven systems and asynchronous workflows • Data + domain modelling strength: Strong ability in data modelling for complex, interdependent business rules, including correctness, consistency, and designing for failure modes. • Product & business alignment: Demonstrated ability to connect technical decisions to business outcomes and customer experience. • First-principles problem solving: Ability to reason from fundamentals (constraints, incentives, data and system behaviour) to design solutions in complex, high-stakes domains. • Navigating ambiguity: Comfort operating in evolving environments, defining direction where it doesn’t yet exist. • Experience in high-performance / high-scale environments (bonus if you’ve used tools like Kubernetes, Spark, or similar). • Delivered a large, complex initiative end-to-end (greenfield or major redesign) with clear business impact. • Experience scaling systems from early product-market fit to multi-product platforms • Experience working closely or as part of Machine Learning teams • Exposure to regulated industries (e.g., energy, fintech, govtech) • Familiarity with real-time pricing engines, workflow orchestration, or AI/agentic systems • Experience improving engineering org design, team topology, or platform strategy
Responsibilities
• Drive Technical Leadership through Execution: Alongside Principal Engineers, you will lead and ship high-impact improvements across Rosso workflows, improving correctness, operability and scalability as volume and complexity grow. • Drive Multi-Team Initiatives: Lead complex, cross-functional efforts across teams and systems - aligning stakeholders and delivering high-leverage outcomes. • Build & Ship: Continue being deeply hands-on in designing, coding, and reviewing critical components across stateful backend services, APIs, and infrastructure. • Strengthen Foundations: Improve reliability and operability, observability, testing strategy, and deployment practices - driving monitoring of service objectives, incident reduction, and operational excellence. • Integrate machine learning models into production: Partner with ML/Data teams to productionise a range of models (including forecasting, optimisation and pricing) safely and effectively within core Rosso workflows. • Design for correctness in complex workflows: Build and evolve pricing and deal-flow workflows where consistency and failure handling are first-class concerns. • Prevent domain drift: Create and maintain clear domain boundaries, shared language, and reduce compounding complexity over time. • Multiply Impact: Mentor Staff and Senior Engineers, raise engineering standards, and act as a trusted technical advisor to leadership. • Plan for Scale: Architect systems to handle high-volume quoting/pricing activity and large customer counts, anticipating bottlenecks before they emerge.
